Grandmother Percys Puzzle Quilt Block

What’s not to love about a quilt block with a name like Grandmother Percy’s Puzzle? As you can see, it’s simply a square in the middle with four triangles placed irregularly around it. It’s a two colour block and I’ve made it here as a 10″ block.

Cutting requirements

2.1/2″ squares: nine white, eight green

2.7/8″ squares: four each in green and white

Making the quilt block

Use the 2.7/8″ squares to make half square triangles. Place a green and a white square with right sides together and mark a line along the diagonal. Sew a 1/4″ seam either side of the marked line and cut along the line to produce two half square triangle units. These are 2.1/2″ squares.

Layout for Grandmother Percys quilt block

Lay the patchwork squares out in five rows of five. There are white squares in each corner and along both diagonals, with two green squares on each edge. Everywhere else there are half square triangles. The trick as ever is to look for the larger patterns to be sure that you place the squares correctly and the most obvious ones are the larger triangles made with one white square and two white triangles.

Sew the squares across each row

Sew the squares together across each row and then sew the rows together to complete the Grandmother Percys Puzzle quilt block.
